UDR Connectivity Control for Regional Overload Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless networks experience network-wide outages due to regional events causing sudden influxes of service requests, leading to UDR overload and cascading failures across the network, with conventional QoS-based solutions being ineffective in containing regional issues.
Innovation Solution
Integrate location information into UDR access interfaces to identify affected geographic areas, allowing core network connectivity managers to instruct backup UDRs to reject service requests from affected regions, thereby containing the overload within the originating region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional QoS-based service rejections are implemented, then service request management is provided, but the impact of regional issues cannot be restricted and cascading failures occur across the entire network
Solution Approach 1:
The patent applies local quality by implementing location-aware service request rejection at individual UDRs. Each UDR monitors service requests from specific geographic areas and can independently reject requests from affected regions while continuing to serve other areas. This localized approach prevents regional issues from cascading network-wide, as each UDR makes independent decisions based on its local service request patterns and location information.
2Reliability
If backup UDRs are used to handle service requests during outages, then service continuity is maintained, but the overload cascades to other geographic areas and causes network-wide failures
Solution Approach 1:
The patent implements preliminary action by proactively monitoring service request patterns and detecting overload conditions before they cascade to backup UDRs. When a UDR detects excessive service requests from a specific location, it preemptively rejects those requests and redirects them to alternative UDRs, preventing the overload from propagating across the network and maintaining overall system capacity.
3Object-affected harmful factors
If location information is integrated into UDR access interfaces, then regional outages can be contained to affected areas, but system complexity increases
Solution Approach 1:
The patent applies universality by integrating location information into existing UDR access interfaces in a multi-functional manner. The same interface that handles service requests also processes and utilizes location information for overload detection and rejection decisions. This approach enables outage containment without requiring separate dedicated interfaces, as the existing interfaces are enhanced to perform multiple functions including location-aware service request management.
Data Source
AI summary
Systems and methods are disclosed for proactively managing core network connectivity to a unified data repository (UDR). A UDR receives service requests from core network entities and monitors associated service performance metrics, which may include location information for the requesting entities. Based on detecting a trend in the monitored metrics, the UDR predicts that a threshold condition indicative of potential service degradation will be met. In response to the prediction, the UDR performs one or more access control actions directed to the affected core network entities prior to detecting that the threshold condition has been met, thereby proactively managing service availability. The access control actions may include rejecting service requests or instructing core network entities not to request service.
